Sometimes in the BIOS this happens, too. At work a few years ago we |
| 38 |
had a Dell laptop where it thought the temperature was 200C degrees |
| 39 |
all the time, so it would run the fan at full speed and go into |
| 40 |
lowest-power mode etc. Once we determined it wasn't really 200C, we |
| 41 |
found out it was a buggy BIOS and upgrading it solved the problem. |
| 42 |
Nobody knows why the laptop worked fine for 2 years and then suddenly |
| 43 |
exhibited this problem, but I was glad to get it fixed so I would stop |
| 44 |
hearing the fan blowing at max speed in the cubicle next to mine. :) |
